ITPEC IP October 2018 Question 13
ITPEC IP October 2018 — Question 13 of 100
A multi-core processor contains multiple processing cores within a single CPU package. The cores can execute different instruction streams at the same time, increasing throughput when the operating system and workload can run tasks in parallel.
Answer (d)
Why not others:
- redundant processors performing identical work describe fault-tolerant duplication
- four cores do not guarantee four times the performance of two cores
- temporarily increasing clock frequency describes boost or turbo operation, not multi-core structure
Key rule: Multi-core improves potential parallelism; its actual gain depends on how much of the workload can execute concurrently.
